1 . A team in Europe are working with wood, but not in the usual ways. They are not carpenters (木匠). Instead, they are scientists exploring how wood can lead to a greener electronic device, a transistor (晶体管) made from balsa wood, whose production releases less climate-warming gas into the air.

Transistors play an important role in computers and other devices. They act like tiny switches to control the flow of electricity. Engineers use them to process and store data. Today’s laptops may host billions of them. So they must be tiny — only a little wider than a strand of DNA.

The new transistor being built by physicist Isak Engquist and his team at Sweden’s Linkoping University isn’t as small as those. Big enough to see and hold, it can stand only an electric pressure that pushes electrons along. And it controls a current using charged particles (粒子) called ions.

This new technology shows a “proof of concept” that the idea can work, even if the new device is not yet ready to put into today’s electronics. “While it seems large by today’s standards, such a transistor still might prove useful for electronics that require low electric pressures,” says Engquist.

“The new transistor suggests that future electronic devices might be made in living plants,” Daniel Simon, a physicist in the team, says. “Imagine peeling away some bark from a living tree,” he says, “and stamping electronic circuits into the living wood.”

In fact, Engquist says, “There are so many ways we can use wood and the components of wood that we would never have thought of.” For instance, he can now imagine a wood-based sensor that could monitor crop health, measure pollution or survey a forest for fire risk.

2 . Walking by Mr. Groll’s yard is the worst part of our morning walk—the unfriendly shape nearby that shades us: Mr. Groll.

“Hello, Mr. Groll.” I _________ him as I do every morning. And he never answers me. But I know he’s there, watching, behind his fence. Why does he _________ me? It’s a mystery (迷). Maybe he’s afraid of me because I’m blind. _________ scare grown-ups sometimes. Then I _________ hearing him playing with my friend Jimmy, who’s in a wheelchair. Maybe Mr. Groll does not like Vietnamese _________. No. Every Saturday Mr. Groll and my big brother, Lien, help each other with yard work.

Me and Chó! An idea _________ my mystery. Maybe I do know why Mr. Groll doesn’t talk to me! So, I attach Chó to a post, and I _________ my way along the fence.

“Mai! Be _________!” Mr. Groll’s loud voice steadies my _________ while his hand steadies my elbow (肘部).

“You solve my mystery. It isn’t because I’m blind that you don’t like me. Or because I am a Vietnamese.” I ________. “It’s Chó who scares.”

He __________ his large voice. “I like you, Mai. And Chó, too. But up close, Chó scares my ________ away,” he says.

I tell him, “Your fear of Chó may be big, but __________ is bigger. We will help. Come with me.” I hear a smile in Mr. Groll’s voice. “OK,” he says, “I __________ you, my friend.”

Then I take Mr. Groll’s hand in mine and guide it to Chó’s head. __________, Mr. Groll pets Chó’s ears. Friendly Chó—good Chó—swings her tail. Our new friendship begins.

3 . Young people are spending more time in digital spaces. The Internet allows us to connect with people, share ideas, be creative, have fun and discover new things. Unfortunately, young people also face risks online. Common problems include cyberbullying (网络欺凌), receiving unwanted messages, seeing images and content you don’t want to see, or having your private information or photos shared without your permission.

Safer Internet Day (SID) is organized in the second week of February every year, and over 180 countries take part. The aim is to raise awareness of online issues and make the Internet a safer place. SID invites everyone to be part of a big conversation about online issues. This is particularly important for teenagers because they often experience unpleasant situations online, but they don’t always feel they can talk about them.

Cyberbullying is when someone uses the Internet to embarrass, threaten or hurt another person. If you experience cyberbullying, talk to an adult you trust as soon as possible. Don’t reply to any messages but save the evidence.

Going online often means spending time alone. When you feel down, social media can make you feel lonelier. Using social media might be related to higher levels of depression. So you need healthy social media use.

Whatever app you use, make sure you know who sees your posts and personal information. Limit what people can see, decide who can comment on your content and thwart other users’ comment. It may be illegal to share a photo or video of someone without their permission. The SID’s website has advice about what to do if someone shares pictures of you that you feel embarrassed about.

There is still a lot we don’t know about how time spent online affects people’s well-being. But talking about all the issues helps everyone understand common problems and know how to deal with them.

1. What can we learn from paragraph 1?

A．The Internet has both good and bad sides.

B．The Internet is a safe place to share photos.

C．Young people should avoid going online.

D．Young people face more risks than adults.

2. What is paragraph 2 mainly about?

A．What we can do on SID.	B．How to take part in SID.

9 . ①The world’s heaviest snake has been hiding a big secret.

② According to a study published today in the open-access journal MDPI Diversity, the animal known as the green anaconda, or Eunectes murinus, is actually two genetically distinct species, despite each species looking so similar that even experts can’t tell them apart.

③“Genetically, the differences are massive,” says Bryan Fry, a National Geographic Explorer, biologist at the University of Queensland in Australia, and coauthor of the new study. “They’re five-and-a-half percent different, genetically. Now, to put that into context, we’re about two percent different from chimps,” he says.

④ To make the shocking discovery, Fry and his coauthors collected blood and tissue samples from green anacondas in Ecuador, Venezuela, and Brazil.The study authors also examined each animal closely to count scales and look for other physical traits that could signal an evolutionary difference. After running the genetic data, they found a clear divide between anacondas sampled in the northern part of the range as opposed to those in the south. And based on those findings, they propose renaming the snakes found in the north as the northern green anaconda (Eunectes akayima), while E. murinus will continue to refer to southern green anacondas.

⑤Fry says his jaw dropped when the analyses completed. “I didn’t expect that level of difference,” he says. “It’s just mind-blowing. We were all of us very much doing happy dances.”

⑥While it may seem like splitting hairs to re-classify two populations of snakes that look identical to one another, Fry emphasizes how important such delineations can be for understanding the threats posed to these creatures. Right now, the International Union for Conservation of Nature classifies the green anaconda as a species of least concern when it comes to extinction risk, but this classification is based, in part, on how widely distributed a species is. “It’s important, because the newly described northern green anaconda has a much smaller range than the southern, and so that means it’s much more vulnerable,” says Fry.

⑦Working with giant snakes isn’t easy. The fact that anacondas are massive, powerful predators is just one reason the animals haven’t been more closely studied. However, more work of this kind may be needed to understand how the northern and southern green anacondas started separate evolutionary tracks. After all, the two species appear to coexist in French Guiana, even as close as being found on opposite riverbanks, says Fry. And yet, there’s no evidence of interbreeding in their genetics.

1. W'hy did the author mention “we’re about two percent different from chimps” in paragraph 3?

A．To show how genetically different green anacondas are.

B．To show how distant we humans are from green anacondas.

C．To show how similar green anacondas are in appearance.

D．To show how hard it is for experts to tell green anacondas apart.

2. Based on the context, what does the underlined word “delineations” in paragraph 6 mean?

A．similarity

B．conservation

C．classification

D．extinction

3. What can be inferred from the passage?

A．Experts suggest continuing to refer to the northern green anacondas as Eunectes murinus.

B．Experts are sure of how green anacondas started different evolutionary tracks.

C．The classification of green anacondas helps arouse awareness of its protection.

D．The two species of green anacondas once interbred in their genetics when living close.

4. Which is the best title of the passage?

A．Eunectes akayima: splitting hairs

B．Eunectes murinus: the world’s heaviest snake

C．Northern green anaconda: a newly found species

D．Green anacondas: two genetically different species

10 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。

One afternoon in August, five years after Mom passed away, I was unpacking my groceries(食品杂货) in my kitchen. When I lifted my left hand out of a grocery bag, I suddenly couldn’t breathe. Looking at the ring on my finger, I found the star sapphire (蓝宝石)was gone. Mom had given me the ring on my twenty-first birthday. I had worn it every day for twenty-nine years. It was a reminder of Mom and a symbol of our love.

“No! No! No!” I yelled, hurrying to check the bag and the floor, and then my car, but the star sapphire was nowhere to be found. Feeling helpless, I called my best friend, Marie. “The star sapphire in my ring fell out. I don’t know what to do,” I said, extremely worried.

Marie replied, “Please don’t be anxious. Try to stay calm and positive. You can go back to the places you just visited and take a look.” But how could I keep hope in seemingly impossible situations? Anyway, I started my car and drove to the grocery store again. I couldn’t shake the feeling that there was little chance that I could find my stone.

Back at the grocery store, I pulled into the same parking spot and looked everywhere for my star sapphire. My hands and knees felt the hot ground as I searched crazily around and under my SUV car. Then I rushed inside the store, searching for a familiar face for more help. I spotted Amanda, a staff member whom I had met on previous shopping trips, and urgently tapped her on the shoulder. “I was just here twenty minutes ago and lost the stone of this ring. It’s very special to me. It’s from my late mom. Could you please help me look for it?” I cried, unaware that many other people around also heard my words.

Amanda’s eyes softened and she nodded understandingly. She immediately took a large mop(拖把) and started carefully sweeping it back and forth down the first aisle (过道) of the huge store.

Paragraph 1:

In tears, I called after her, “It’s light blue and small.”

Suddenly, a customer near the counter excitedly called out loudly, “Oh, Madam, I’ve found it!”.
